Yet as you say, we can imagine God not existing too. So that tells us little. The universe's nonexistence may not be impossible, like the link says, but it also hasn't been shown that God's isn't.
That depends on how they're defining the universe. If modal realism is true, then the universe (in the ultimate sense of the term) is necessary (by such reasoning), because it can be argued you can't logically have the absence of Existence existing.
